It is a claim that has been around for a couple of years now, and one I have repeated in various places, including this blog.
Keith and I both once worked for the Journal Inquirer, and he is an excellent reporter who works very hard to verify his facts. You can trust his reporting. And yes, he has proven unequivocally that I -- along with many others, including the Connecticut Business & Industry Association and the Yankee Institute for Public Policy -- have repeatedly promoted what turns out to be an erroneous statement.
You can read his story here.
That said, what also is quite obvious from Keith's reporting is that, while Malloy did not impose the two largest tax increases in state history, he DID approve TWO OF THE LARGEST tax increases in state history. At worst, they were two of the top 6 largest;
So while critics can no longer claim Malloy approved the two biggest tax increases, they can say the tax increases he approved were among the highest approved by any recent governor.
That's not a great legacy, regardless of where he ranks.
